CHURCH OF ENGLAND PENSIONS BOARD / SWEDISH NATIONAL PENSION FUNDS COUNCIL ON ETHICS REQUEST FOR INFORMATION CONCERNING TAILINGS MANAGEMENT

PREAMBLE

a) Provide an overview of your tailings management system, and how you manage risk

The most significant waste materials produced by our operations are tailings, waste rock, chemical waste and hydrocarbon waste. By managing these wastes responsibly, we minimise the environmental and potential social impact, so as to maintain our licence to operate.

In total, as at 7 June 2019, our ten operations (including three joint venture sites) contain 34 tailings dams, of which 14 are active or are being rehabilitated and one will be commissioned imminently. With regards to active tailing storage facilities (TSFs), Gold Fields currently has two in-pit tailings dams operating at Agnew (Australia) and St Ives (Australia), five downstream/centreline tailings dams and seven upstream tailings dams. Gold Fields operations with active downstream/centreline tailings dams are Cerro Corona (Peru), Damang (Ghana) and Tarkwa (Ghana). Gold Fields has only three operations where upstream tailings are being used, being South Deep (South Africa), Tarkwa and Granny Smith (Australia). The factor of safety (FOS) of each existing upstream TSF is regularly reviewed, and when required, modification options (e.g. embankment buttressing) are considered to ensure Gold Fields’ target minimum FOSs are at least sustained.

Maintaining our TSFs, which includes identifying, assessing and managing the risks associated with them (including operational, structural and environmental risks) is part of our ordinary course of business. That notwithstanding, Gold Fields, like many other mining companies faces inherent risks in our operation of TSFs. Most critically, tailings must be disposed of in an appropriate manner so as not to impact the safety of the workforce and communities or cause environmental damage. The use of TSFs exposes Gold Fields to certain risks, among them seepage of decanted tailings water or and the failure of a dam at a tailings storage facility.

TSFs designed with upstream constructed embankments typically present greater risk, particularly where the facility is located in a high seasonal rainfall area and where the embankments are constructed using reclaimed tailings materials. The occurrence of a at one of Gold Fields’ TSFs could also lead to the loss of human life and/or extensive property, environmental damage and result in significant financial exposure and the approach we take to prevent such a failure is described on the following pages.

Gold Fields’ Group, regional and mine management regularly assess the risks facing the business. The assessments of the risks and their mitigating actions are a critical internal management tool, which seek to mitigate the identified risks. Risk mitigations are included in the annual Group Performance Scorecard and cascaded down to the performance scorecard of management employees at regional and operational levels. The formal risk review process starts during management’s annual strategic planning sessions where strategic risks and macro-trends are analysed in developing Gold Fields’ risk registers and mitigating actions. These are updated quarterly, and presented to the Board’s Risk Sub-Committee twice a year for verification.

Gold Fields maintains measures to manage its TSFs’ safety, including compliance with the International Council on Mining & Metals’ (ICMM) Tailings Governance Position Statement and undertakes routine reviews by independent international consulting companies.

All of our operations have tailings management plans in place, including closure and post-closure management plans. Gold Fields has implemented a multi-layered approach to TSF management that includes:

1. TSFs are designed by external, experienced and qualified engineers 2. TSF designs are required to be peer-reviewed 3. Construction is supervised or monitored by the design engineer and includes appropriate quality assurance/control 4. “As-built” facilities are required to be signed-off by the design engineer 5. TSFs are managed by assigned personnel 6. TSFs have an engineer of record appointed who undertakes regular reviews of the TSFs 3

7. Independent audits are undertaken at least on a triannual basis (more often in some cases) 8. Gold Fields’ corporate technical services team review and check TSF management processes employed at the operations 9. Key variances identified by TSF reviews are noted and communicated to the Gold Fields Executive Committee and the Board of Directors quarterly 10. Gold Fields has developed a formal Group TSF Management Guideline, and full compliance to this is expected 11. Risk is identified formally through risk assessments undertaken at various stages of the design and operational process 12. A strategic risk register is maintained at corporate level, which includes risks linked to the TSFs

Gold Fields is moving away from installing new upstream TSFs with the most recent new TSFs constructed being in-pit TSFs (Agnew and St Ives), and downstream TSFs (Gruyere (Australia), Tarkwa and Damang).

As two of our sites - South Deep and Granny Smith - are located in relatively dry regions, limited amounts of water need to be stored on the facilities, significantly reducing the risk of saturation of the dams. Tarkwa’s upstream tailings dams in Ghana have been constructed from imported fill materials, and are designed assuming worst-case scenario conditions, to ensure the embankments remain stable throughout both the wet and dry seasons, as well as for the life of the facility.

All Gold Fields’ TSFs, as well as associated pipeline and pumping infrastructure, are subject to an independent, external audit every three years – or more frequently where required by local circumstances or regulations – as well as regular inspections and formal annual or quarterly Engineer of Record reviews.

Risk tables and heat maps have been published in the Integrated Annual Report (IAR) for the last nine years. See https://www.goldfields.com/reports/annual-report-2018/risks-and-materiality.php for more details. Information about how Gold Fields discloses risks associated with its TSFs may be found in its most recent Form 20-F filing with the US Securities and Exchange Commission. See https://www.goldfields.com/form-20- f.php for more details. b) Confirm whether your approach to tailings management has changed or will change in light of the recent tailings disasters at Brumadinho, Mariana, Mt Polley and others. Have you, for example, reviewed all tailings storage facilities with upstream dam construction, and taken steps necessary to protect local communities and the environment e.g. buttressing, evacuation?

After the Samarco accident, ICMM members developed a Tailings Position Statement in 2016 and approved a tailings aspirational goals roadmap in late 2018. Following a company-wide programme of internal and external reviews of the Gold Fields TSFs undertaken in 2017, a number of improvement areas were recommended, including:  Seismicity design considerations  Appointment of an Engineer of Record for each TSF  Dam break assessments  Update of emergency response plans  TSF seepage management and control

Gold Fields’ Group Tailings Management Guidelines are aligned to the ICMM Tailings Position Statement. The guidelines were strengthened during 2017 with the inclusion of additional performance guidance and minimum assessment criteria.

Subsequent to the Brumadinho tragedy, the ICMM agreed to establish an independent panel of experts to develop an international standard for tailings facilities for its member companies. The panel has since been established.

In addition to closing out the above identified gaps during 2018, Gold Fields also embarked on a programme to further improve operational safety of its TSFs, including moving away from the construction of upstream facilities to centre-line or downstream designs, consideration of filtered and dry stacked tailings, as well as in-pit tailings disposal.

These are in line with the main areas of work under the ICMM’s aspirational goals: improving critical controls and reducing tailings water content.

The following actions have been implemented or are currently in process at our operations: • The recent construction of a new downstream TSF for the Damang Reinvestment project • The adoption of filtered, dry stacked and lined tailings storage for the planned Salares Norte () mine • The increased use of in-pit tailings disposal in Australia (new TSFs for Agnew and St Ives installed are in- pit TSFs) • Increased use of tailings for underground backfill at the South Deep, Granny Smith and St Ives Invincible mines • Improved governance over seepage control at TSFs through the installation of liners. All new TSFs at Tarkwa, Damang and Gruyere are fully or partially lined

In February 2019, the Gold Fields Board also requested strengthened governance of the Group’s TSFs through, among others, quarterly TSF update reports, continuous environmental monitoring, satellite monitoring scans, and increased external and independent verification. These programmes and initiatives are currently being investigated by management with a view to rapid implementation.

Gold Fields is also working with Lepanto Mining, its majority partner in the Far Southeast project in the Philippines, on enhancing risk mitigating measures for the TSF used by Lepanto for tailings disposal from its nearby gold mine. Gold Fields and Lepanto have commissioned external consultants to undertake detailed hydrological, seismic and geotechnical reviews and make recommendations on strengthening the TSF. The TSF is located in a region with high seismic activity and frequent typhoons.

Our technical teams are also working with Asanko Gold to further strengthen risk assessment and governance of the lined and downstream designed TSF at the Asanko gold mine joint venture in Ghana. Asanko Gold has management control of the operation.

During 2018, two new downstream TSFs were commissioned at our West African operations: the FETSF at the Damang mine and TSF 5 at Tarkwa. c) General note

ICMM agreed a position statement on the materiality of member submissions, which it relayed to the Church of England and the Swedish Council of Ethics. Gold Fields has applied the same interpretation to our response.

To fulfil our understanding of the spirit of the questionnaire (i.e. any potential latent life-safety concerns at an existing facility that have been previously flagged but remain unaddressed), the following interpretation has been used:  Not being certified/confirmed as stable is assumed to be where a noted deficiency is deemed sufficiently significant to trigger a catastrophic failure – the term deficiency is used in that context herein;  For operating facilities, this refers to any identified sufficiently significant deficiency for the current life/stage. For a previous life/stage, any deficiency that was not addressed as vetted by an independent review  For closed/legacy facilities, this refers to any identified sufficiently significant deficiency that reflects the current state of the facility versus a previous issue that has been addressed through a confirmed changed condition via the closure process

We have applied the above interpretation because we believe the disclosure effort is aimed at identifying tailings facilities that could potentially lead to a life-safety concerns, while avoiding falsely identifying issues for facilities that are decades old and no longer resemble the facility referred to in a former noted deficiency (i.e. the formerly noted deficiency is of a nature that materially no longer exists).
